A patient who stops taking an ACE inhibitor because of its side effects will begin taking an angiotensin II receptor blocker (ARB) medication. Which side effect of ACE inhibitors will not occur with an ARB medication?
Dry cough
Hyperkalemia
Hypotension
Angioedema
The Correct Answer is A
Choice A reason: ACE inhibitors cause dry cough by inhibiting bradykinin breakdown, which accumulates and irritates the airways. ARBs block angiotensin II receptors without affecting bradykinin, eliminating this side effect. This makes ARBs a suitable alternative for patients experiencing cough, confirming this as the correct choice.
Choice B reason: Hyperkalemia occurs with both ACE inhibitors and ARBs due to reduced aldosterone production, which decreases potassium excretion. Both drug classes affect the renin-angiotensin-aldosterone system similarly, so switching to an ARB does not eliminate this risk, making this choice incorrect for the question.
Choice C reason: Hypotension is a shared side effect of ACE inhibitors and ARBs, as both reduce blood pressure by inhibiting the renin-angiotensin system. ARBs block angiotensin II receptors, causing vasodilation similar to ACE inhibitors, so this side effect persists, making this choice incorrect.
Choice D reason: Angioedema, though rare, can occur with both ACE inhibitors and ARBs. While less common with ARBs, it’s not eliminated, as it may result from mechanisms beyond bradykinin accumulation. Switching to an ARB doesn’t guarantee avoidance of angioedema, making this choice incorrect.

Correct Answer is D
Explanation
Choice A reason: Insulin glargine is a long-acting insulin given once daily, not twice daily. Morning and 4:00 PM dosing is typical for intermediate-acting insulins, so this incorrect for glargine’s schedule.
Choice B reason: Rapid-acting insulins are given before meals, not glargine, which provides basal coverage. Glargine is dosed once daily, so this is incorrect.
Choice C reason: Post-meal or after meals and bedtime dosing does not suit glargine’s 24-hour action. It’s given once daily, typically at bedtime, so this is incorrect for the administration timing.
Choice D reason: Insulin glargine is administered once daily, often at bedtime, to provide steady basal insulin coverage for 24 hours. This aligns with its pharmacokinetics, making it the correct choice.
Correct Answer is A
Explanation
Choice A reason: Patient weight: 198 lbs ÷ 2.2 = 90 kg. Dose: 1 mg/kg × 90 kg = 90 mg. Volume: 90 mg ÷ (30 mg/0.3 mL) = 90 × 0.3/30 = 0.9 mL. This delivers the correct anticoagulant dose for conditions like DVT, making it the accurate choice.
Choice B reason: For 90 kg (198 lbs ÷ 2.2), the dose is 90 mg. Volume: 90 mg ÷ (30 mg/0.3 mL) = 0.9 mL. Choice B (1.2 mL) delivers 120 mg (1.2 × 30/0.3), overdosing Lovenox, increasing bleeding risk, making it incorrect.
Choice C reason: The correct volume for 90 mg is 0.9 mL (90 ÷ 30 mg/0.3 mL). Choice C (0.6 mL) delivers 60 mg (0.6 × 30/0.3), underdosing Lovenox, reducing anticoagulant efficacy, which could fail to prevent thrombosis, making this choice incorrect.
Choice D reason: For 90 mg, the volume is 0.9 mL. Choice D (0.3 mL) delivers 30 mg (0.3 × 30/0.3), significantly underdosing Lovenox for a 90 kg patient, risking inadequate anticoagulation and thrombotic events, making this choice incorrect.
